Representative embodiments are directed to systems and methods for processing analyzer trace data of a multi-tone signal to more accurately estimate the frequencies and amplitudes of the tones of the multi-tone signal. Specifically, trace data may be processed to determine peak trace points. For eac...

A new phasing scheme for multitone signal systems to reduce peak‐to゛verage power ratio 来自 Wiley 喜欢 0 阅读量: 39 作者:S Narahashi,T Nojima 摘要: This paper proposes a new phasing scheme to achieve a very small peak-to-average power ratio (PAPR) of multitone signals. With this ...
This paper describes two new artificial frequency mapping techniques suitable for the simulation of RF/microwave mixers when excited by a multi-tone signal. Due to the gained computational efficiency, it is for the first time possible to simultaneously analyze small and large signal behavior of nonli...
Therefore the approach of multi-tone signal injection is implemented in which multiple frequency responses could be measured in only one time-domain measurement. In linear loads, the multi-tone approach could give the same results with single-tone approach because superposition holds for linear system...
Various embodiments associated with signal classification are described. A repeating signal can be partially corrupted and therefore a receiver can obtain an incomplete signal. In one example, the incomplete signal can have discontinuous unobstructed segments. In order for the receiver to understand the ...
A telephone system for transmitting either a dial pulse signal or a dual-tone multifrequency signal along a telephone line. This telephone system includes a switching means for changing between a KEY signal from a key board and a control signal from a CPU. When a power interruption sensing mea...
